Application filed ,Tune 21, 1920. Serial No. 390,312.

To all whom t may concern.'

Be it known that I, CHARLEs H. Garn, a citizen of the United States,residing at Cincinnati, in the county of Hamilton and State of Ohio,have invented certain new and useful lmprovements in Bed-Springs, ofwhich the following is a specification.

My invention concerns features of novelty and advantage inspi'ingcusl1ion constructions, especially, but not necessarilyrestrictedly, in bed-springs embodying a plurality of uprightspiral-springs which support the load.

One leading aim of the invention is the provision of a structure of thiskind in which the springs may be locally depressed by a load withoutsubstantial effect on the neighboring springs, whereby the occupancy ofone side of the bed-spring by one person will have little, if any,influence on the companion occupant of the other side of the spring. 1nother words, the bed-spring is so constructed as to eliminate anytendency for the occupants to roll toward the center of the bed or thelighter weight occupant toward the one of heavier weight.

Further objects of the invention are the production of a bed-spring ofthis kind which possesses adequate resiliency, which is noiseless, whichis relatively simple in structure, which has a suitable transversecrown, and which is comparatively economical to manufacture.

ln order that those skilled in this art may have a full and completeunderstanding of the invention, both from structural and functionalstandpoints, a preferred and desirable embodiment of the same has beenillustrated in the accompanying drawings which should be considered inconnection with the following detailed description of the structure andits mode of operation and throughout the several views of which likereference characters refer to the same parte.

ln these drawings:

Figure 1 is a bottom plan view of the bedspring;

F ig. 2 is a vertical cross-section through the bed-spring on anenlarged scale;

Fig. 3 is a fragmentary longitudinal sec tion on line 3-3 of Fig. 2; and

Fig. 4 is a fragmentary enlarged crosssection at the center of thespring.

Referring to these drawings, it will be seen that the bed-springcomprises a rectangular frame 10 including longitudinal side-bars 11, 11of lZ-shape in cross-section and endbars 12, 12 of similar form incrosssection, which frame may be constructed in any approved manner.rfhe middle portions of the lower, inwardly-extended flanges 13 of suchcross end-bars are connected together by an intermediate, longitudinal,angle-bar 14, having one flange horizontally disposed and resting on andfastened to the flanges 13, 13 and having its companion flange arrangedvertically as is clearly indicated in lFigs. 2 and 4. Fastened to theunder faces of the inturned flanges 15 of the side-bars 11, 11 and tothe bot-tom face of the horizontal flange of bar 14, are two spaced',hollow, transverse-bars 16 and 17 of any desired shape in cross-section,whereby the frame as a whole is provided with six openings between thevarious intersecting or crossing bars.

The lower flange 15 of each frame sidebar p intermediate bar by the'clips which engage goles in the upright flange of such latter Thesecross-wires, which are crimped at intervals as shown in, Fig. 2, areassociated at such spaced points with similarly# crimped, parallel,longitudinal wires 22, which are omitted 4at the `cross-bars 16 and 17.Thus, there are three sets of such lengthwise wires throughout thelength of the frame. lt will be appreciated, there* fore, that thisunderlying, yielding supporting structure is divided into six sections,each being supported only crosswise-of the frame, the wires 22 beingwholly unconnected with the frame. By reason of this construction, thewires '22 may be depressed without conflict or interference with theintermediate cross-bars, these interlaced wires at rightangles to oneanother constituting a flexible or pliable foundation or fabric on whichthe greater portion, but not all, of the upright spiral-springs aremounted.

At each intersection or crossing of the lsupporting wires 18 and 22 anupright spiralspring 23 is mounted thereon in the'. usual manner, suchsprin s in elevation having the shape shown in igs. 2 and 3 resemblingsomewhat an hour-glass form. ln addition, a middle row 24 ot suchsprings is mounted directly on the top edge of the central bar 14, beingheld from displacement by the associated clips 21. All around the framecloses'such marginal springs which are se-A cured to it by metalfasteners 29 oi any suitable and convenient form, and the upper or topcoils or convolutions of all of the spiral-springs 23, 2d and 26areconnected together asshown .by short, helical springs 30 of theconstruction set forth in my earlier United States Patent No. 1,263,548.e

lhe spiral-springs 23 and 2d oi the cross rows at their waists, or atabout one-halt oi their height, are connected together by crimped ordeformed, dat, metal-bands 31 which extend unintemiptedly from theoutermost spring 23 on one side ot the structure to the corresponding`spring on the other side. Such metal straps are associated withlongitudinal wires 32 interloched therewith. at the springs and alsolocked with such' springs. Thus the upright disposition oi the manysprings is assured at all times,

but it is to be noted that none of the elements 31 and 32 are connectedto the trame.

lt will' be perceived that by reason oi' the downward and 4oppositesloping or the sectional, underlying, supporting structure .com-posed ofthe interloclied members 18 and 22 from the center-bar 1d to the framelside-bars, the top surface of the bed-spring fis givenv the propervtransverse crown or arch to overcome sagging in the middle or centralzone, and the avoidance of such obv jectionable depression is furtherfostered or aided by mounting the central or middle row of springs 24on'the fixed or non-yielding support 14.

In addition, a will be observed that ,bg

i supplying the border of the bed-spring wit the shorter, ruprightspiral-springs supported directly on the brackets fastened to the frame,a desirable stiffer margin .for the bed-spring is secured, whereby aperson seated on the edge portion thereof does not -unduly depress it.

To those skilled in this art it will be apparent that the invention isnot limited and restricted to the precise and exact details of structureillustrated and described, but rather that these mayv be modified withintacones comparatively wide limits without departure from the heart andsubstance of the invention and Without the sacrice of any of itssubstantial benefits and advantages. Stated somewhat diderently, theinvention is susceptible of a'variety of embodiments of which the onepresented is merely a convenient example.v
